Hi, thanks I think now I understand how it works...
I m using now this code for the first specie in all my transect IDs. df.s <- split(Baumdaten, list(Baumdaten$transectID, Baumdaten$Baumart), drop = TRUE) head(names(df.s), 10) "A_SEF_Abies alba" "A_LEF_Abies alba" "B_SEF_Abies alba" "B_LEF_Abies alba" "C_SEF_Abies alba" "C_LEF_Abies alba" "D_SEF_Abies alba" "D_LEF_Abies alba" "E_SEF_Abies alba" "E_LEF_Abies alba" But can you tell me how, I can make subsets out of one of the subsets. For example I want boxplot for the variable age. Is it something like this? It dosent work, I know... lapply(df.s,boxplot(A_SEF_Abies alba$Baumart)) Thanks in advanced -- View this message in context: http://r.789695.n4.nabble.com/computing-a-subset-using-a-loop-tp4636564p4636653.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
